Yeah, Green unfortunately has the stigma of where he was drafted, the circumstances of the trade, his salary, and also unfair expectations to deal with.
This part I still don't understand. He's paid like the third-best player on a reasonable team, and he's fully capable of being one. On any recent championship team, he would have been no better than the fourth-highest paid player. I'm more and more inclined to think that it is some fans and not Jeff Green that have to deal with something
Jeff Green's PER this season is 13.8 (league average 15). Humphries, Sullinger, Crawford, Bass, Rondo, Lee all have a higher PER than 13.8, so you can argue Jeff is not even the third best player in terms of efficiency, and we are not even a team that shines in PER this season.
